* Rename is_private to is-private as ordered by DT policy. The change leaves the support for the old format. * Add is-memcpu property, so it is possible to enable memory-to-memory transfers support via DT. * Add hw-llp property, so it is possible to enable hardware multi block transfers support via DT. Fix white spaces.
